Description

The present invention relates to a light irradiation device. More specifically, the present invention is used as a foil pressing tool in a foil pressing device that transfers a desired pattern or the like to a medium using a foil film, an optical pointer used when pointing to a desired position by light, or the like. The present invention relates to a suitable light irradiation device.

In the present specification, the term "media" refers to not only various recording media made of paper such as plain paper, but also resin materials such as PVC and polyester, and various types such as aluminum, iron, wood, cloth, and leather. Materials shall be included.

Conventionally, there has been known a foil pressing device in which a desired pattern or the like is transferred to a medium by transferring the foil film to a medium using a foil film.

FIG. 1 shows a schematic configuration perspective explanatory view of a foil pressing device according to a conventional technique. The foil pressing device 100 shown in FIG. 1 is driven in response to an input from the computer 102, and performs a foil pressing process on the media 104 by a foil pressing drive program stored in the computer 102.

The foil pressing device 100 is provided with a slidable table 108 on the front side and the rear side on the upper surface of the flat plate-shaped base member 106, and a foil film (not shown) is provided on the table 108. A holding member 110 for holding the media 104 and the like is provided.

Further, on the rear side of the base member 106, a support member 112 erected in a gate shape is provided, and the support member 112 is provided with sliders 114 slidably provided on the left side and the right side. Has been done.

Further, the slider 114 is provided with a slider 116 slidably provided on the upper side and the lower side, and the foil pushing tool 118 is gripped on the slider 116.

As the foil pressing tool, for example, a pen that is a light irradiation device that emits laser light as light from the tip portion (in the present specification, a pen that is a light irradiation device that emits laser light as light from the tip portion) is referred to as a “laser pen”. (Appropriately referred to as) or a pen in which the copper member at the tip is heated by a nichrome wire or a ceramic heater (in the present specification, a pen in which the copper member at the tip is heated by a nichrome wire or a ceramic heater”. Is appropriately referred to as a "heat pen").

The laser pen generates heat by the laser light emitted from the tip portion, thereby transferring the foil film to the medium.

With such a configuration, in the foil pressing device 100, the relative positional relationship of the foil pressing tool 118 with respect to the foil film and the media 104 held by the holding member 110 can be moved in the three-dimensional direction.

In the above configuration, when the media 104 is subjected to the foil pressing process, the media 104 is held by the holding member 110 in a state where the computer 102 and the foil pressing device 100 are activated.

Next, the foil film is fixedly placed on the media 104 by the holding member 110, and the foil pressing process is executed by the foil pressing device 100 by the foil pressing drive program stored in the computer 102.

Then, the foil pressing device 100 scans the foil pressing tool 118 based on the graphic data stored in the computer 102 while pressing the tip of the foil pressing tool 118 onto the media 104 via the foil film.

At this time, the heat generated by the foil stamping tool 118 transfers (thermally transfers) the foil film to the region on the media 104 where the tip of the foil stamping tool 118 is pressed by the heat and pressure generated by the foil stamping tool 118. , The media 104 will be stamped with foil.

In the foil stamping process by the foil stamping device 100, the graphic product formed on the media 104 has a metallic feeling and a high-class feeling due to gloss, which are difficult to express by a process such as general printing.

By the way, the conventional laser pen is provided with a condensing lens for condensing the laser light guided by the optical fiber as a tip member for pressing the foil by contacting and pressing the foil film. Then, under the control of a computer, the laser light source was controlled so that the laser beam having the power density (intensity) required for foil stamping was emitted at the timing when the condenser lens reached directly above the foil stamping point on the foil film. ..

That is, according to the conventional laser pen, the laser light having a large power density required for foil pressing could be emitted regardless of the pressing state. Therefore, when the pen tip is floating from the foil film, the laser light having a large power density is emitted. There is a problem that it is dangerous if the reflected light is reflected by the foil film and gets into the eyes of the operator (Problem 1: Danger due to the reflected light).

Further, according to the conventional laser pen, as described above, the laser beam having the power density required for foil pressing is emitted regardless of whether or not the foil film is actually pressed by the laser pen. A situation is likely to occur in which the relationship between the pressing pressure of the laser pen on the film and the power density of the laser light is not appropriate, and in that case, the foil pressing in the desired region cannot be performed and the foil pressing quality is deteriorated. (Problem 2: Deterioration of foil pressing quality).

Further, in the conventional foil stamping device, in order to improve the work efficiency of the operator, when the foil stamping portion on the foil film is indicated by light and positioned, an optical pointer such as a laser pointer is provided separately from the laser pen. There is a need. Therefore, there is a problem that the configuration becomes complicated and the manufacturing cost increases (problem 3: complicated configuration).

Furthermore, when an optical pointer such as a laser pointer is provided separately from the laser pen as described above, the optical axis of the laser light emitted from the laser pointer and the optical axis of the light emitted from the optical pointer do not match. It shifts. Therefore, there is a problem that it is not easy to perform accurate positioning on the foil film (problem 4: difficulty in positioning).

Since the prior art that the applicant of the present application knows at the time of filing the patent application is not an invention related to an invention known in the literature, there is no prior art document information to be described in the specification of the present application.

The present invention has been made in view of the above-mentioned various problems of the prior art, and an object of the present invention is the above-mentioned various problems, that is, the danger due to reflected light and the foil pressing quality.

In order to achieve the above object, the present invention makes the tip member of the light irradiation device movable, detects the movement of the tip member due to pressing, and controls the intensity of light emitted from the light source based on the detection result. It is something that I tried to do.

Therefore, according to the present invention, it is possible to control the intensity of the light emitted from the light source so as to be the intensity required for the foil pressing at the timing when the tip member of the light irradiation device is pressed by the foil film and moved.

For this reason, it is possible to prevent the high-intensity light required for foil pressing from being obliquely emitted with the pen tip floating and being reflected by the foil film, eliminating the danger of the reflected light from the foil film. be able to.

Further, it is possible to appropriately set the relationship between the pressing force of the tip member against the foil film and the light intensity, and it is possible to prevent deterioration of the foil pressing quality.

Furthermore, when the tip member is pressed and not moving, the light source is controlled so that the tip member outputs light with a weak intensity that is not dangerous to the human body, so that the foil is pressed without incurring the complexity of the configuration. Positioning can be performed by showing the location with light.

Furthermore, since the optical axis of the light indicating the foil stamping location and the optical axis of the light at the time of foil stamping coincide with each other, accurate positioning on the foil film can be easily performed.

That is, according to the present invention, in a light irradiation device that emits light from a tip portion, a hollow housing, a light source that supplies light into the housing, and one end of the housing to the other end side. A tip member that is movably arranged and emits light supplied into the housing, an urging means that has a urging force that urges the tip member to one of the ends, and the tip member. Based on the detection means for detecting that the light has moved from one end to the other end side against the urging force of the urging means, and the detection result of the detection means, the light of the light source It is provided with a control means for controlling the light source so as to change the intensity.

Further, in the present invention described above, the present invention has an optical system for condensing the light supplied into the housing to the tip member.

Further, in the present invention, the above-mentioned optical system is composed of a pair of lenses arranged so that the convex surfaces face each other.

Further, in the present invention described above, the tip surface of the tip member is formed in a substantially hemispherical shape so that the light supplied into the housing is focused on the top of the tip surface. It is the one that was made.

Further, in the present invention described above, when the tip member moves from one end to a preset position on the other end side against the urging force of the urging means. The light supplied into the housing is focused on the top of the housing.

Further, in the present invention, the control means has a light intensity lower than a preset value when the detection result of the detection means indicates a state in which the tip member is not moving. When the detection result of the detection means indicates a state in which the tip member is moving, the light source is controlled so that the light intensity is higher than the preset value. It is designed to be controlled.

Further, in the present invention described above, the light source is a laser light source.

Since the present invention is configured as described above, it is possible to solve various problems in the prior art, that is, the danger due to reflected light, the deterioration of foil stamping quality, the complexity of the configuration, and the difficulty of positioning. It has an excellent effect of being able to do.

For convenience of explanation, in the paper surface of FIGS. 2 to 4, the position in the upper end side direction of the paper surface is referred to as “upper side”, and the position in the lower end side direction of the paper surface is referred to as “lower side”.

The laser pen 10 as an example of the embodiment of the light irradiation device according to the present invention is arranged in a substantially cylindrical housing 12 whose central axis direction extends in the vertical direction and on the lower end side of the housing 12. The housing is connected to the tip member 14, the optical fiber 16 having one end 16a connected to the upper end side of the housing 12, and the other end 16b of the optical fiber 16 by injecting laser light into the optical fiber 16. A laser light source 18 for supplying laser light to the inside of the housing 12, an optical sensor 20 arranged on the lower side of the housing 12, and a control unit 30 are included.

The control unit 30 is composed of, for example, a microcomputer or the like. The laser light source 18 is controlled so as to change the power density (intensity) of the emitted laser light by the control of the control unit 30 based on the detection result of the light sensor 20.

Reference numeral 32 is a cable that connects the optical sensor 20, the control unit 30, and the laser light source 18.

Here, the light intensity can be measured using, for example, "Field Max II manufactured by COHERENT (model number PS19)".

More specifically, the housing 12 has a substantially cylindrical shape with a hollow inside. One end 16a of the optical fiber is connected to the opening 12a on the upper side. Inside the housing 12, a housing taper-shaped portion 12b whose diameter is tapered downward is formed at a position below the laser light emitting surface 16aa at one end 16a of the optical fiber 16. The upper opening 12ba of the housing tapered shape portion 12b is formed to have substantially the same diameter as the laser light emitting surface 16aa. Below the housing taper shape portion 12b, an optical system arrangement portion 12c extending with substantially the same diameter as the lower opening portion 12bb of the housing taper shape portion 12b is formed. That is, the upper opening 12ca and the lower opening 12cc of the optical system arrangement portion 12c are formed to have substantially the same diameter as the lower opening 12bb. Below the optical system arrangement portion 12c, a movable member moving region 12d formed having a diameter larger than that of the lower opening portion 12cc is formed. The lower end of the movable member moving region 12d, which is the lower end of the housing 12, protrudes toward the inner diameter side, and the protrusion 12da in the inner diameter direction is formed.

A plano-convex lens 26 and a plano-convex lens 28 constituting the optical system are arranged in the optical system arrangement unit 12c. More specifically, in the upper opening 12ca of the optical system arrangement portion 12c, the incident surface (upper side surface) of the laser light emitted from the laser light emitting surface 16aa is formed by the plane 26a, and the emitting surface (lower side) is formed. A plano-convex lens 26 whose side surface) is formed by the convex surface 26b is arranged. Further, in the lower opening 12cc of the optical system arrangement portion 12c, a plano-convex lens 28 having an incident surface (upper side surface) of laser light formed by a convex surface 28a and an emitting surface (lower side surface) formed by a flat surface 28b. Are arranged. That is, the plano-convex lens 26 and the plano-convex lens 28 constituting the optical system are arranged so that the convex surface 26b, which is the exit surface of the plano-convex lens 26, and the convex surface 28a, which is the incident surface of the plano-convex lens 28, face each other.

The laser pen 10 is provided with a movable member 22 that can move in the vertical direction within the movable member moving region 12d. The movable member 22 is formed with an upper opening 22aa having substantially the same diameter as the lower opening 12cc, and a movable member tapered shape portion 22a whose diameter is tapered downward. Below the lower opening 22ab of the movable member tapered shape portion 22a, a tip member arranging portion 22c that extends with substantially the same diameter as the lower opening 22ab and opens at the lower end surface 22b is formed. The upper opening 22aa of the movable member 22 is formed with an outer diameter projecting portion 22d that projects toward the outer diameter side and can come into contact with the inner diameter direction projecting portion 12da. In the movable member moving region 12d, the outer diameter direction protruding portion 22d and the inner diameter direction protruding portion 12da come into contact with each other, so that the movable member 22 is held in the movable member moving region 12d without falling from the housing 12. ..

The tip member 14 is fixedly arranged in the tip member arranging portion 22c so that the tip surface 14a projects downward from the lower end surface 22b. The tip surface 14a of the tip member 14 is formed in a substantially hemispherical shape. During the foil pressing process, the tip surface 14a comes into contact with the foil film F. Further, the tip member 14 is made of a light-transmitting material (for example, quartz glass or acrylic resin) that transmits laser light.

The spring fixing portion 12e formed along the vertical direction on the outer diameter side of the optical system arrangement portion 12c in the housing 12 and the upper surface of the outer diameter direction projecting portion 22d are widened in the vertical direction. An urging spring 24 is arranged. By the urging force of the spring 24, the outer diameter direction protrusion 22d is urged in the direction of being pressed against the inner diameter direction protrusion 12da. Therefore, when no load is applied to the tip member 14 or the movable member 22 in the direction of pushing the tip member 14 or the movable member 22 into the movable member moving region 12d of the housing 12, as shown in FIG. In addition, the outer diameter direction protrusion 22d and the inner diameter direction protrusion 12da are in contact with each other. On the other hand, when a load is applied to the tip member 14 and the movable member 22 in a direction of pushing the tip member 14 and the movable member 22 into the movable member moving region 12d of the housing 12 against the urging force of the spring 24, The tip member 14 and the movable member 22 move upward in the movable member moving region 12d. As shown in FIG. 4, this movement is stopped when the outer radial direction protrusion 22d and the lower end face portion 12cc of the lower opening 12cc come into contact with each other.

An optical sensor 20 is arranged at a position below the lower opening 12 kb in the housing 12. The optical sensor 20 is composed of a light emitting element 20a and a light receiving element 20b arranged so as to face each other in a direction orthogonal to the axial direction of the housing 12, that is, in a radial direction. When the light emitting element 20a and the light receiving element 20b are in contact with the outer diameter direction protrusion 22d and the inner diameter direction protrusion 12da (see FIG. 3), the light emitted from the light emitting element 20a is the light receiving element. In a state where light can be received by the light receiving element 20b and the protrusion 22d in the outer radial direction and the lower end surface portion 12cc are in contact with each other (see FIG. 4), the light emitted from the light emitting element 20a is received by the light receiving element 20b. They are arranged in a positional relationship that cannot receive light.

That is, in a state where the outer diameter direction protrusion 22d and the inner diameter direction protrusion 12da are in contact with each other (see FIG. 3), there is no shield between the light emitting element 20a and the light receiving element 20b, so that the light emitting element The light emitted from the 20a can be received by the light receiving element 20b.

On the other hand, the tip member 14 and the movable member 22 move upward in the movable member moving region 12d against the urging force of the spring 24, and the outer radial direction protrusion 22d and the lower end surface portion 12cc are in contact with each other. In (see FIG. 4), the movable member 22 acts as a shield between the light emitting element 20a and the light receiving element 20b, and the light emitted from the light emitting element 20a cannot be received by the light receiving element 20b.

The control unit 30 controls the output of the laser light source 18 so as to change the power density of the laser light emitted by the laser light source 18 based on the detection result of the light sensor 20. Specifically, when the detection result of the optical sensor 20 indicates that the light receiving element 20b is receiving the light emitted from the light receiving element 20a, the control unit 30 has an intensity lower than a preset value. The output of the laser light source 18 is controlled so that the tip member 14 emits a laser beam having a power density (a power density lower than the power density required for foil pressing) that does not affect the human body. Further, when the detection result of the optical sensor 20 indicates that the light receiving element 20b does not receive the light emitted from the light receiving element 20a, the control unit 30 determines that the light intensity is higher than the preset value. The output of the laser light source 18 is controlled so that the laser light focused on the top 14aa (described later) of the tip member 14 has the power density required for foil pressing.

Here, the intensity of light that does not affect the human body is "JIS C 6802 class I" in the case of laser light.

The urging force of the spring 24 is such that when the tip member 14 is pressed against the foil film F by the optimum pressing force during the foil pressing process, the outer radial direction protrusion 22d and the lower end surface portion 12cc are in contact with each other. It is preferable to set as such. The optimum pressing force means a pressing force at which an appropriate foil pressing process is performed without damaging the foil film. If the pressing force is too strong, the foil film may be damaged, and if the pressing force is too weak, the proper foil pressing process cannot be performed.

Next, FIGS. 5A and 5B show an optical path explanatory diagram showing the optical system of the laser pen 10. For example, when the optical system is arranged in the dimensions shown in FIGS. 5A and 5B, the plano-convex lens 26 and the plano-convex lens 28 have a diameter D1 of 10 mm and a focal length of 10 mm. It is preferable to set the dimensions to. Further, it is preferable to set the dimensions of the tip member 14 so that the diameter D2 is 4 mm and the radius of curvature of the tip surface 14a is 2.5 mm.

In the optical system of the laser pen 10, when the outer diameter direction protrusion 22d and the inner diameter direction protrusion 12da shown in FIG. 3 are in contact with each other, the laser light emitted from the tip surface 14a of the tip member 14 becomes parallel light. On the other hand, in a state where the outer radial protruding portion 22d and the lower end surface portion 12cc shown in FIG. 4 are in contact with each other, the laser beam is designed to be focused on the top portion 14aa on the tip surface 14a of the tip member 14.

The laser pen 10 is not limited to the dimensional setting as shown in the present embodiment, and the tip of the laser pen 10 is in contact with the outer diameter direction protrusion 22d and the inner diameter direction protrusion 12da shown in FIG. The laser light emitted from the tip surface 14a of the member 14 becomes parallel light, while the outer radial projecting portion 22d shown in FIG. 4 and the lower end surface portion 12cc are in contact with each other, and the tip surface 14a of the tip member 14 is in contact with the laser light. As long as the laser beam is designed to be focused on the top 14aa, the dimensions may be set appropriately, and an optical system may not be provided.

In the above configuration, for example, a case where the laser pen 10 is attached to a conventionally known foil stamping device as described with reference to FIG. 1 to perform foil stamping processing will be described.

Even if the foil pressing process is started, if no load is applied in the direction of pushing the tip member 14 or the movable member 22 of the laser pen 10 into the movable member moving region 12d of the housing 12, the urging force of the spring 24 is used. The outer diameter direction protrusion 22d and the inner diameter direction protrusion 12da are in contact with each other. In this state, since there is no shield between the light emitting element 20a and the light receiving element 20b, the light emitted from the light emitting element 20a can be received by the light receiving element 20b. Therefore, the control unit 30 controls the laser light source 18. , Laser light having a power density that does not affect the human body is emitted from the tip member 14 as parallel light. Since this parallel light has a power density that does not affect the human body, there is no danger that the reflected light from the foil film F will affect the human body.

Therefore, when the foil pressing portion on the foil film F is indicated by light and positioned, the parallel light emitted from the above-mentioned tip member 14 is used without providing an optical pointer such as a laser pointer separately from the laser pen 10. be able to. Further, since the optical axis of the parallel light coincides with the optical axis (condensing position) of the laser light focused on the top 14aa of the tip surface 14a, accurate positioning can be performed on the foil film F. can.

When the tip surface 14a of the tip member 14 is pressed against the foil film F and the tip member 14 and the movable member 22 move upward in the movable member moving region 12d against the urging force of the spring 24, the outside The radial protrusion 22d and the lower end face portion 12cc are in contact with each other. In this state, the movable member 22 serves as a shield between the light emitting element 20a and the light receiving element 20b. Therefore, since the light receiving element 20b cannot receive the light emitted from the light receiving element 20a, the laser light source 18 controls the laser light source 18 to emit the laser light having the power density required for foil pressing. It is focused on the top 14aa.

The urging force of the spring 24 is set so that when the tip member 14 is pressed against the foil film by the optimum pressing force during the foil pressing process, the outer radial direction protrusion 22d and the lower end surface portion 12cc are in contact with each other. If this is done, the foil film F can be pressed by an optimum pressing force in a state where the laser beam is focused on the top 14aa of the tip surface 14a of the tip member 14.

Therefore, it is possible to appropriately set the relationship between the pressing force of the tip member 14 with respect to the foil film F and the power density of the laser beam, and it is possible to prevent deterioration of the foil pressing quality.
